Internal WiFi/Bluetooth Module
This internal card handles all 802.11 wireless handshakes. In V-Series models, these modules are known to fail, resulting in the TV being unable to 'see' any networks or intermittently dropping connections. Replacing this individual board is the standard surgical fix when software resets and SSID changes fail.

Main Board
If the WiFi module is functional but the TV UI shows 'WiFi Off' or cannot toggle the setting, the logic bus on the Main Board that communicates with the wireless card has failed. This assembly must be replaced if the internal USB/PCIe lanes for networking are unresponsive.

USB-to-Ethernet Adapter
A common field workaround when internal WiFi modules are out of stock or the main board bus is damaged. It allows the TV to bypass internal networking components to gain internet access via the USB port, provided the firmware supports external LAN drivers.
